Context History (more history, all contexts)

Start Date Context Status Description
2024-09-09 hst_1180.pmap operational Delivery of new STIS CCD bias and dark reference files for CCD data taken between April 17 and June 17, 2024. The files were generated from data taken in the same time frame under STIS calibration programs 17378 and 17376. A recent analysis showed that the Lyman alpha gain sag holes on COS FUVB at LP5, which also appear at LP6, have gotten wider and are no longer being appropriately flagged. As such, a new COS GSAGTAB was delivered to account for these larger holes.
2024-09-05 hst_1178.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated follow the ACS WFC anneal on August 31, 2024, and should be used to calibrate ACS WFC observations taken between August 04, 2024 and August 31, 2024.
2024-08-22 hst_1177.pmap archived The new build of CalCOS applies a Y walk correction that is a function of YCORR rather than XCORR, as was previously the case. This means that the COS YWLKFILE must have dimensions 1024x32 instead of 16384x32. The COS YWLKFILE we are delivering here was previously delivered to crds-test as part of hst_1165.pmap, and used for regression testing, so we know this reference file works with the new build of CalCOS. In a few months, we will replace this COS YWLKFILE with a YWLKFILE that applies a correction that is dependent on the YCORR coordinate. This file affects all COS FUV data taken in TIME-TAG mode.
2024-08-22 hst_1176.pmap archived These WFC3 UVIS superdarks will affect all UVIS data taken from July 15, 2024 to August 10, 2024, and this new bad pixel table with USEAFTER of July 15, 2024 was generated using data taken from July 16, 2024, through August 13, 2024. These WFC3 UVIS drk and dkc files were generated using dark exposures from HST Cycle 31 CAL program 17349. More information regarding the method used to create the UVIS dark calibration reference files can be found in WFC3 ISR 2016-08. Additionally, the header of each reference file contains a detailed history section outlining the process, and provides a list of data used to create each file. These WFC3 UVIS bad pixel files were generated using 900 second dark exposures from the HST 31 daily monitoring programs 17345, 17348, and 17349. More information about the UVIS bad pixel tables is outlined in the WFC3 ISR 2018.15 and WFC3 ISR 2021.14.
